EM6325CXSP5B-3.1+

Supervisors Overview

The EM6325CXSP5B-3.1+ is an ultra-low current reset circuit manufactured by EM Microelectronic, designed for portable and battery-operated devices. It monitors supply voltage between 1.5V and 5.5V, generating a reset signal after a fixed timeout when VDD rises above the threshold. Key parameters include a 200ms reset timeout, 2.9μA supply current at 3.3V, and -40°C to +125°C operating temperature. The device features a manual reset input with internal pull-up, ±1.5% threshold accuracy, and 2.1% hysteresis. This specific variant offers a 3.1V threshold, active-low push-pull output, and SC70-5L packaging.

Supervisors Feature Summary

• Manual reset function via dedicated input with internal pull-up
• Ultra-low supply current consumption for battery efficiency
• Immunity to short negative supply transients
• Guaranteed valid reset signal down to low voltage levels

Supervisors Applications

• Portable electronic devices
• Battery-operated systems
• Embedded system power monitoring

Supervisors Procurement Notes

Verify the suffix '3.1+' indicates the specific 3.1V threshold voltage configuration. Confirm the 'C' package code corresponds to SC70-5L and 'X' denotes the active-low push-pull output option. Ensure RoHS compliance matches project requirements. Cross-reference the exact part number against manufacturer databases to confirm availability of this specific pinout and electrical specification combination before finalizing procurement.

Supervisors Selection Notes

Select this component when a 3.1V reset threshold is required for systems operating within the 1.5V to 5.5V range. Choose the SC70-5L package for space-constrained designs. Opt for this variant if an active-low push-pull output is necessary. Consider the 200ms timeout period relative to system stabilization needs. Verify that the manual reset feature aligns with the system's control logic requirements.

Supervisors Part Context

The EM6325 series comprises ultra-low current reset circuits available in various configurations. This model belongs to the EM6325 family, which includes multiple threshold voltages and output options. The series is characterized by small packages like SC70 and SOT23, making it suitable for compact applications. The EM6325CXSP5B-3.1+ represents a specific configuration within this flexible family, tailored for precise voltage monitoring tasks.

Supervisors Replacement Considerations

Check for other EM6325 variants with different thresholds or output types if the 3.1V threshold or active-low push-pull output does not match the design. Verify pin compatibility with alternative packages such as SC70-4L or SOT23-5L if physical footprint changes are permissible. Ensure substitute parts maintain similar supply current and operating temperature specifications.
